SMOKE-CONSUMING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 257,606, dated May 9,1882.

Application filed January 9, 1882. (No model.)

,To all whom it may concern:

Be it known that we, SIDNEY PARKER and JAMES D. BENNETT, both of thecity of Chicago, in the county of Cook and State of lilinois, haveinvented a new and useful Apparatus for .Cousuming Smoke in Furnaces;and we hereby declare the following tobe a full. clear, and exactdescription thereof, which will enable'others skilled in the art towhich our invention relates to make and use the same,

reference being had to the accompanying drawin gs, forming a parthereof, and in which Figure 1 represents a side view of a steamboilerand furnace with our apparatus attached.

I Fig. 2 represents a trout view of the same. Fig. 3 represents a frontview of the. apparatus 1) with its cover removed. Fig. 4 represents aside view of the apparatus D in section, on A the line .10 a", with itscover and inlet and exhaust pipesf and h. Fig. 5 represents an endsectional. view taken on the line 3 3 Like letters of reference indicatelike parts.

The object of our invention is to produce a smoke-consuming apparatus,situated within the furnace of a boiler above the fire, by means of ajet of steam operating upon the flame and exhaust of the apparatus; h,the cover of the apparatus D, and i a channel around the top of the sidewalls of the heater D, and j a corresponding head on its cover h.

It represents the wire screens covering the openings 12, made atalternate ends through the partition-walls Z. i

The exhaust-pipe g has a slot, m, extending along the entire length ofthe outerside of the T-shaped exhaust.

The top It is firmly bolted to the apparatus D, and the channel i ispacked with asbestus or other heat-resisting substance, so as to make asteam-tight joint.

The apparatus D is placed on the inside of the furnace-wall, andpreferably a little from it, so that heat may pass up between it and thefurnace-wall, so as to thoroughly heat it, and thus superheat thepassing steam, and thereby give it increased force and dryness'by thetime it comes in contact with the smoke and gases. The screens 7c retardthe steam as it passes from one chamber a into another, and therebysubject it to greater heat befor it finally emerges from the slot at.

The apparatus 1) is made of cast-iron, to which the cover It is stronglybolted, as shown, andits place in the furnace may be more or less to thefront or rear along theside walls; or a series of them may be fastcnedto both sides and front of the furnace-walls. A bridgewall,'c, is placedacross the rear of the furnace for the purpose of retarding the smoke,which would otherwise be urged into the chim ney too rapidly and partlydeft-at the object sought.

What we claim as new is The apparatus D, formed of one solid piece ofcast-iron, and provided with partition-walls l, dividing it intochambers 12, having open-75 ings p at alternate ends of saidchambers,-provided with screens, channel '5, and iuletf, in combinationwith cover h, provided with bead j, and T-shaped exhaust provided withslot'm,

substantially as specified.
